Bibcode:2007ASAJ..122L..52A. doi:10.1121/1.2761883. ISSN 0001-4966. PMID 17927307. The absolute threshold usually starts to increase sharply when the signal frequency exceeds about 15 kHz. ... The present results show that some humans can perceive tones up to at least 28 kHz when their level exceeds about 100 dB SPL.
